dynamic graphics cursor shapes
enables applications to change the shape of the graphics cursor to indicate the
state of the application. For example, the graphics cursor typically changes shape
when a user drags an object or rotates a plot.
Using a Mouse in the SAS Windowing Environment under z/OS
The IBM 3179G, 3192G, 3472G, and 5550 terminals are all graphics terminals that
support the use of a mouse. The IBM 3179G, 3192G, and 5550 terminals use the
three-button IBM 5277 Model 1 optical mouse, whereas the IBM 3472G terminal uses
the two-button PS/2 mouse.
SAS recognizes when the mouse is attached and automatically places the graphics
cursor under the control of the mouse.
Using a Three-Button Mouse
The IBM 5277 Model 1 optical mouse has three buttons:
leftmost button
SAS uses the leftmost button as an ENTER key. The ENTER key is used to select
menu items; to grow, shrink, or move windows; to scroll using scroll bars; and so
on. Therefore, having the ENTER key on the mouse is useful. The text cursor
moves to the location of the mouse cursor whenever you press this mouse button.
center button
By default, SAS assigns a function key to the center button. You can use the
KEYS window or the KEYDEF command to change the definition of this button.
The button is designated as MB2. See the help for Base SAS for more information
about the KEYS window and the KEYDEF command.
rightmost button
The rightmost button is a reset button that unlocks the keyboard.
For additional information about using a mouse, refer to the appropriate
documentation at your site.
Using a Two-Button Mouse
The 3472G terminal is a multiple-session graphics terminal. This device uses the
two-button PS/2 mouse. With the graphics cursor attached, these buttons have the
same functions as the leftmost and center buttons on the three-button mouse.
Appearance of Window Borders, Scroll Bars, and Widgets
Depending on the type of terminal, SAS uses either programmed symbols or APL
symbols to create window borders, scroll bars, and widgets (radio buttons, push buttons,
and check boxes). This can cause SAS windows to look somewhat nicer on some
terminals than on others.
3 On devices that support programmed symbols, the SAS windowing environment
uses a predefined set of programmed symbols for its window components.
Programmed symbols give window components a nicer appearance than APL
symbols. These programmed s ymbols are available for the four most common
character cell sizes: 9 x 12, 9 x 14, 9 x 16, and 6 x 12. Programmed symbols are
not used for any device that has a different character cell size (for example, 10 x
14 on a Tektronix 4205), even though the device supports programmed symbols.
